Description
Tube aus weichgestelltem Kunststoff für flüssiges oder pastenförmiges Füllgut Die Erfindung bezieht sich auf eine Tube aus weichgestelltem Kunststoff für flüssiges oder pastenförmiges Füllgut, deren beide Enden durch Querschweißnähte geschlossen sind und die an der einen Querschweißnaht einen verschließbaren Entleerungsansatz hat. Tube made of plasticized plastic for liquids or pastes Filling material The invention relates to a tube made of plasticized plastic for liquid or paste-like filling material, both ends of which are welded across the sides are closed and the one transverse weld has a closable drainage attachment Has.
Neben Tuben aus Zinn od. dgl. sind bereits Tuben aus weichgestelltem Kunststoff bekanntgeworden. In addition to tubes made of tin or the like, there are already tubes made of softened material Plastic became known.
Eine solche bekannte Kunststofftube wird aus einem weichgestellten Kunststoffschlauch hergestellt, wobei am Entleerungsende eine durch spiralige Rippen verstärkte, daher wie bei den Zinntuben starre kreisförmigeSchulter gebildet wird, die einenKunststoffschraubhals mit Schraubkappe trägt. Die starre Schulter dieser bekannten Tube erschwert die restlose Entleerung der Tube, und zudem wird nach dem Auspressen und vor dem Wiederverschließen Luft in den Tubeninnenraum eingesaugt, da die starre Schulter nach dem Nachlassen des Preßdruckes beim Entleeren eine Wiedervergrößerung des Tubeninnenraumes durch die Elastizität des Tubenwerkstoffes begünstigt.Such a known plastic tube is made from a plasticized one Plastic hose made, with a spiral rib at the discharge end Reinforced, therefore rigid, circular shoulder is formed as with the tin tubes, which has a plastic screw neck with screw cap. The rigid shoulder of this one known tube complicates the complete emptying of the tube, and also after the Squeezing out and before reclosing air sucked into the interior of the tube, because the rigid shoulder is enlarged again after the compression pressure has been released during emptying of the tube interior favored by the elasticity of the tube material.
Ferner ist eine Tube aus Kunststoff bekanntgeworden, deren Tubenkörper aus an den Längsrändern miteinander verklebten, tiefgezogenen Halbschalen besteht. Am Entleerungsende ist ein vorgefertigter Kunststoffschraubhals mit Schraubkappe angesetzt, der keinen oder nur einen sehr kleinen Befestigungsflansch besitzt. Selbst wenn die Halbschalen aus einem sehr dünnen Kunststoffblatt hergestellt sind, bewirkt die vorgenommene Verformung, daß die Schulterpartie dieser Tube wie eine starre Schulter wirkt. Somit treten auch hier die Nachteile der zuerst beschriebenen Tube auf. Furthermore, a tube made of plastic has become known, the tube body consists of deep-drawn half-shells glued together at the longitudinal edges. At the emptying end there is a prefabricated plastic screw neck with a screw cap attached, which has no or only a very small mounting flange. Self when the half-shells are made from a very thin sheet of plastic the deformation carried out that the shoulder part of this tube like a rigid one Shoulder works. Thus, the disadvantages of the tube described first also occur here on.
Ferner sind Tuben aus Kunststoff bekanntgeworden, die aus einem vorher gefüllten langen Kunststoffschlauch kettenartig abgeschweißt werden. Am Entleerungsende ist entweder ein Fortsatz mit einem kleinen Querschlitz vorgesehen, wodurch ein selbstschließender Verschluß entsteht, der sich durch Abbiegen des Fortsatzes öffnen läßt, oder aber es ist ein langer Hals ausgebildet, der nach dem erstmaligen Öffnen durch Umknicken und Festlegen in dieser Stellung den Verschluß des Tubeninhalts sichern soll. Furthermore, tubes made of plastic have become known from a previously filled long plastic hose are welded like a chain. At the end of emptying either an extension with a small transverse slot is provided, whereby a self-closing closure is created, which can be opened by turning the extension leaves, or there is a long neck formed, which after the first opening by bending and fixing in this position the closure of the tube contents should secure.
Diese bekannten Tuben, bei denen zwar die Nachteile der bekannten Kunststofftuben vermieden sind, gewährleisten aber keinen absolut sicheren Verschluß des Tubeninhalts. So kann der eine selbstschließende Verschluß sich beim Transport durch Druckanwendung und gleichzeitiges Abbiegen des Fortsatzes ungewollt öffnen. Beim umgeknickten Zungenverschluß kann sich die Klammer ungewollt lösen, und die Entleerungsöffnung der Zunge kann verschmutzen, so daß z. B. ein steril zu haltendes Füllgut unbrauchbar wird.These known tubes, although the disadvantages of the known Plastic tubes are avoided, but do not ensure an absolutely secure closure of the tube contents. So the one self-closing closure can be during transport open unintentionally by applying pressure and at the same time bending the extension. When the tongue lock is bent over, the clip can unintentionally loosen and the The emptying opening of the tongue can get dirty, so that, for. B. a sterile to be kept Filling material becomes unusable.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Tube aus weichgestelltem Kunststoff zu schaffen, die einfach und billig herstellbar ist sowie zum absolut sicheren Verschließen des Tubeninhalts mit einem Schraubverschluß ausgerüstet ist, wobei eine vollständige Entleerung des Füllgutes ermöglicht und die Gefahr des Einsaugens von Luft nach dem Auspressen und vor dem Wiederverschließen vermieden wird. The present invention is based on the object of a tube to create from plasticized plastic that is easy and inexpensive to manufacture as well as for the absolutely safe closing of the tube contents with a screw cap is equipped, which allows a complete emptying of the contents and the risk of air being sucked in after pressing out and before resealing is avoided.
Die diese Aufgabe lösende Tube ist nach der Erfindung gekennzeichnet durch einen kleinen oder nur einen sehr kleinen Befestigungsflansch besitzenden Kunststoffschraubhals mit Schraubkappe, welcher am Behälterkörper in Überdeckung mit der einen Querschweißnaht befestigt ist und bei dem mindestens der Befestigungsflansch aus weichgestelltem Kunststoff besteht. The tube that solves this problem is characterized according to the invention by having a small or only a very small mounting flange Plastic screw neck with screw cap which overlaps the container body with which one transverse weld seam is fastened and with at least the fastening flange consists of plasticized plastic.
Bei der erfindungsgemäßen Ausführung wird die überraschende Feststellung ausgenutzt, daß die weiche Tubenschulter, wenn die Tube mit flüssigem oder pastenförmigem Füllgut gefüllt ist, eine hinreichende Steifigkeit erhält, um der einen Hand des Benutzers als Angriffspunkt zu dienen, wenn die andere Hand die Schraubkappe vom Schraubhals abschraubt. Die übliche starre Schulter, die die auf- gezeigten Nachteile mit sich bringt, konnte somit entfallen. In the embodiment according to the invention, the surprising finding is exploited that the soft tube shoulder when the tube with liquid or paste-like Filling product is filled, is given sufficient rigidity to one hand of the To serve as a point of attack when the other hand pulls the screw cap off Unscrews screw neck. The usual rigid shoulder that the shown Brings disadvantages, could thus be omitted.
Diese Versteifungswirkung kann noch verstärkt werden, indem man absichtlich den Druck des Füllgutes auf die Innenflächen der Schulterung sowie das Beharrungsvermögen der Masse dieses Füllgutes erhöht dadurch, daß man sie unter zeitwiligem Druck auf den Tubenkörper beim Auf- bzw. Abschrauben der Schraubkappe zum oberen Ende strömen läßt. This stiffening effect can be increased by intentionally the pressure of the product on the inner surfaces of the shoulder and the inertia the mass of this product is increased by being under temporary pressure the tube body flow to the upper end when the screw cap is screwed on or off leaves.
Die Erfindung wird nachfolgend an Hand der in der Zeichnung dargestellten Ausführungsbeispiele näher beschrieben. In dieser zeigen Fig. 1 und 2 zwei Aufrisse in Vorder- und Seitenansicht einer ersten Ausführungsform der fertigen gefüllten Tube, Fig. 3 eine perspektivische Ansicht der Tube und des Ansatzes vor dem Zusammenbau, Fig. 3a eine andere Form des Gewindeansatzes als diejenige in Fig. 3, Fig. 4 einen Schnitt der beiden Teile beim Zu-Zusammenbau, Fig. 5 und 6 das obere Ende einer Abänderung der erfindungsgemäßen Tube in Daraufsicht bzw. im Schnitt nach der Linie VI-VI, Fig. 7 die Anordnung der Tube im Schnitt. The invention is illustrated below with reference to the in the drawing Embodiments described in more detail. In this, FIGS. 1 and 2 show two elevations in front and side views of a first embodiment of the finished filled Tube, Fig. 3 is a perspective view of the tube and the extension before assembly, 3a shows a different form of the thread attachment than that in FIG. 3, FIG. 4 Section of the two parts when to-assemble, Fig. 5 and 6 the upper end of a Modification of the tube according to the invention viewed from above or in section along the line VI-VI, Fig. 7 shows the arrangement of the tube in section.
Die in Fig. 1 dargestellte Tube 1 besteht aus einem biegsamen rohrförmigen Teil aus Kunstharz, z. B. aus formbarem Polyvinylchlorid, das mittels Hochfrequenzstrom verschweißt worden ist. Diese Tube wird bei ihrer Herstellung gefaltet und nach zwei Faltlinien 2 und 3 geschlossen, die in zwei zueinander senkrechten Ebenen liegen. The tube 1 shown in Fig. 1 consists of a flexible tubular Part made of synthetic resin, e.g. B. of malleable polyvinyl chloride, which by means of high frequency current has been welded. This tube is folded during its manufacture and after two fold lines 2 and 3 closed, which lie in two mutually perpendicular planes.
Der Schweißverschluß 2 ist wie üblich gerade, die Schweißlinie 3 dagegen weist eine besondere Form auf, d. h., sie geht entlang zweier zueinander in einem stumpfen Winkel geneigter Linien 3-3', und am Scheitel dieses Winkels ist ein eigens hergestellter Gewindeansatz 4 angeordnet, der mit einem Verschlußteil 5 in üblicher Weise versehen ist. The weld closure 2 is straight, as usual, the weld line 3 however, has a special shape, i. i.e., it goes along two to each other lines inclined at an obtuse angle 3-3 ', and at the apex of this angle is a specially made threaded extension 4 arranged with a closure part 5 is provided in the usual way.
Die Erfahrung hat gezeigt, daß die so hergestellte Tube, wenn sie mit einem pastösen Stoff, einer Flüssigkeit oder sogar nur mit Luft gefüllt ist, eine hinreichende Steifigkeit aufweist, damit die beiden Schweißlinien 3 und 3' eine genügend starre Schulterung darstellen, um der einen Hand des Benutzers als Anhalt zu dienen und der Drehbeanspruchung beim Auf- und Abschrauben der Verschlußkappe an den bzw. von dem Gewindeansatz4 Widerstand zu leisten. Experience has shown that the tube produced in this way, if is filled with a pasty substance, a liquid or even just with air, has sufficient rigidity so that the two weld lines 3 and 3 ' represent a sufficiently rigid shoulder to be used by one hand of the user Stop to serve and the torsional stress when screwing on and unscrewing the cap to offer resistance to or from the threaded attachment 4.
Andererseits erhöht die Anordnung der Faltlinien 2 und 3-3' in zwei zueinander senkrechten Ebenen das Fassungsvermögen der Tube und gibt ihr ein gefälligeres Aussehen. Doch ist dieser Umstand nicht unbedingt nötig, da die Schweißlinie 2 in derselben Ebene liegen kann wie die Linie 3-3'. On the other hand, the arrangement of the fold lines 2 and 3-3 'increases in two mutually perpendicular planes the capacity of the tube and gives it a more pleasing one Appearance. But this fact is not absolutely necessary because the welding line 2 in may lie on the same plane as the line 3-3 '.
Fig. 3 und 4 zeigen eine einfache und wirtschaftliche Ausführungsform der eben beschriebenen Tube. 3 and 4 show a simple and economical embodiment the tube just described.
Der rohrförmige Teil ist zuerst durch später zu beschreibende Mittel, wie in Fig. 3 dargestellt, hergerichtet, d.h., er bleibt unten offen, entsprechend der Schweißlinie 2, dagegen ist er oben so ausgeschnitten, daß die schrägen Schweißlinien 3 und 3' miteinander durch eine annähernd in der Achse der Tube angeordnete Verlängerung 6 verbunden sind. The tubular part is first by means to be described later, as shown in Fig. 3, prepared, i.e. it remains open at the bottom, accordingly the welding line 2, on the other hand it is cut out at the top so that the oblique welding lines 3 and 3 'with each other by an extension arranged approximately in the axis of the tube 6 are connected.
Über diese Verlängerung 6 erfolgt nun die Vereinigung mit dem Ansatz 4. Dieser Ansatz besteht z. B. aus einem einfachen Zylinderstück mit Innenbohrung, das von einem laufenden Rohr, womöglich aus einem Preßstoff ähnlich dem, aus dem der biegsame Behälter 1 selbst besteht, der aber starrer ist als letzterer, abgeschnitten ist.This extension 6 is now used to combine with the approach 4. This approach consists e.g. B. from a simple cylinder piece with an inner bore, that from a running pipe, possibly from a molding material similar to that from which the flexible container 1 itself consists, but which is more rigid than the latter, cut off is.
Der Teil 4 braucht nicht unbedingt an beiden Enden offen zu sein. Er kann auch eine Art Fingerhut 4 a darstellen (Fig. 3 a) , der eine nicht durchgehende Bohrung aufweist. The part 4 does not necessarily have to be open at both ends. He can also represent a kind of thimble 4 a (Fig. 3 a), the one that is not continuous Has bore.
In beiden Fällen kann der Zusammenbau der Tube 1 mit dem Ansatz 4 über die Verlängerung 6, wie in Fig. 4 dargestellt, erfolgen. Der Ansatz 4 wird zuvor in eine Matrize 7 eingesetzt, die eine Bohrung von ungefähr gleicher Abmessung aufweist wie der Durchmesser des Ansatzes 4, aber bei 8 ein Innengewinde besitzt. In die Bohrung 9 des so eingesetzten Ansatzes 4 führt man die Verlängerung 6 des vorher zugerichteten Teiles der Tube 1, und in diese Verlängerung 6 hinein führt man eine Elektrode 10, die so ausgebildet ist, daß sie eine Schulterung 10 a darstellt, die sich an dem Ende der Schweißlinien 3 und 3' abstützt, wobei sie die Verlängerung 6 in der Bohrung 9 hält. Die Matrize 7 selbst stellt eine von einem Hochfrequenzstrom gespeiste Elektrode dar. In both cases, the assembly of the tube 1 with the extension 4 via the extension 6, as shown in FIG. 4. Approach 4 will previously inserted into a die 7, which has a bore of approximately the same size has like the diameter of the extension 4, but has an internal thread at 8. In the bore 9 of the approach 4 used in this way, the extension 6 of the leads previously trimmed part of the tube 1, and into this extension 6 leads into it one an electrode 10, which is designed so that it represents a shoulder 10 a, which is supported at the end of the welding lines 3 and 3 ', being the extension 6 holds in the bore 9. The die 7 itself constitutes one of a high frequency current powered electrode.
Wenn man nun einen Strom von hoher Frequenz zwischen den Elektroden 10 und 7 herstellt, erzielt man die Verschweißung der Zitze 6 mit der Innenfläche der Bohrung 9 des Ansatzes 4. Die durch den Hochfrequenzstrom erzeugte Wärme bewirkt zugleich ein Erweichen bzw. das Schmelzen der ganzen Masse des Ansatzes 4, und dies hat zur Folge, daß ihre Randfläche in das Gewinde 8 eindringt und dessen Form annimmt. Will man übrigens ein Innengewinde erzielen, so würde es genügen, eine innen glatte Elektrode 7 und im Gegensatz dazu eine mit Gewinde versehene Elektrode 10 vorzusehen. If you now have a current of high frequency between the electrodes 10 and 7, the teat 6 is welded to the inner surface the bore 9 of the approach 4. The heat generated by the high frequency current causes at the same time a softening or melting of the whole mass of the approach 4, and this has the consequence that its edge surface penetrates the thread 8 and assumes its shape. Incidentally, if you want to achieve an internal thread, it would be sufficient to use a smooth one on the inside Electrode 7 and, in contrast, a threaded electrode 10.
Nach Herausnahme der Elektroden und Abkühlung kann das Ganze mit Bezug auf die Elektrode 7 durch Abschrauben des Ansatzes 4 von den Gewinden 8 abgenommen werden. After removing the electrodes and cooling down, the whole thing can be done with Relation to the electrode 7 is removed by unscrewing the attachment 4 from the threads 8 will.
Falls man einen Ansatz von der in Fig. 4a dargestellten Art verwendet, öffnet man nach beendigtem Schweißen die nicht durchgehende Bohrung dieses Ansatzes. Die Tube ist nun gebrauchsfertig, d. h., sie kann von hinten gefüllt und nach der Füllung durch eine Schweißlinie 2 verschlossen werden. If one uses an approach of the type shown in Fig. 4a, the non-continuous bore of this approach is opened after the welding is finished. The tube is now ready for use, i. i.e., it can be filled from the back and after the Filling can be closed by a weld line 2.
Das Herrichten des rohrförmigen Teiles 1 (Fig. 3) kann in folgender Weise vor sich gehen: Die einzelnen Teile 1 erhält man durch Abschneiden aus einem laufenden, vorzugsweise vorher aufgeblasenen Rohr, so daß sie senkrecht zu den schrägen Schweißlinien 3 und 3' eine gewisse Wölbung aufweisen, die das Fassungsvermögen der Tube vermehrt und ihr zugleich ein gefälligeres Aussehen verleiht. Die Schweißung nach 3-6-3' kann bei aufeinanderliegenden Rändern oder auch flach vorgenommen werden, doch muß dann der überschüssige, sich aus der Schweißung ergebende Stoff (Fig. 3 punktiert) abgeschnitten werden. Man benutzt bei der Herstellung der erfindungsgemäßen Tube vorzugsweise ein Verfahren, daß es ermöglicht, ein Verschweißen Rand an Rand ohne einen bzw. mit nur einem geringfügigen Verbindungsstreifen direkt zu erzielen. Die einzelnen aus einem laufenden Rohr abgeschnittenen Teile 1 können vorzugsweise hintereinander in derselben Richtung angeordnet sein, d. h., auf das offene hintere Ende eines Teiles folgt das vorbereitete Ende 3-6-3' des nächsten Teiles. The preparation of the tubular part 1 (Fig. 3) can be done in the following Way to go about it: The individual parts 1 are obtained by cutting from one running, preferably previously inflated tube so that it is perpendicular to the slopes Welding lines 3 and 3 'have a certain curvature that the capacity the tube increases and at the same time gives it a more pleasing appearance. The weld after 3-6-3 'can be done with overlapping edges or flat, but then the excess material resulting from the weld (Fig. 3 dotted) are cut off. One used in the preparation of the invention Tube preferably a process that enables edge-to-edge welding without directly achieving one or with only a slight connecting strip. The individual parts 1 cut off from a running pipe can preferably be arranged one behind the other in the same direction, d. i.e., on the open rear At the end of one part, the prepared end 3-6-3 'of the next part follows.
Gemäß der Erfindung ist es vorteilhafter, die Einzelteile entgegengesetzt gerichtet hintereinander herzurichten, d. h., der hergerichtete Teil 3-6-3' eines Tubenteiles steht dem Teil 3-6-3' des vorhergehenden Tubenteiles gegenüber. Dank dieser Anordnung kann man zugleich das Verschweißen der Teile 3-6-3' zweier aufeinanderfolgender Tubenteile erzielen, indem das Aufblasen der Tube zugleich die Wölbung der beiden einander gegenüberliegenden und gleichzeitig verschweißten Teile 3-6-3' sichert. Fig. 5 bis 7 zeigen eine andere Ausführungsform der Tube, die besonders bei Tuben aus einem Stoff wie Polyäthylen anwendbar ist, die bei Hochfrequenz sich nicht verschweißen läßt. According to the invention it is more advantageous to oppose the items directed one behind the other to prepare, d. i.e., the prepared one Part 3-6-3 'of a tube part is the part 3-6-3' of the preceding tube part opposite to. Thanks to this arrangement, the parts 3-6-3 'can be welded at the same time. two successive tube parts can be achieved by inflating the tube at the same time the curvature of the two opposite and welded at the same time Secures parts 3-6-3 '. Fig. 5 to 7 show another embodiment of the tube, which is particularly applicable to tubes made of a material such as polyethylene, which is used at high frequency cannot be welded.
In diesem Fall ist der Ansatz 4 vorzugsweise mit einem kleinen Bund 12 versehen (s. Fig. 5 und 6), derart, daß die Dicke der Tube dadurch nicht verstärkt wird. Auf diesen Bund wird das Ende der Schulterung 3-3' der zuvor hergerichteten Tubenteile aufgeschweißt. Dabei entfällt die Verlängerung 6, da die beiden Schulterungen 3-3' voneinander durch eine Öffnung getrennt sind, in die der Ansatz 4 bis zum Bund 12 hineingesteckt ist. In this case, the approach 4 is preferably with a small collar 12 (see Figs. 5 and 6) in such a way that the thickness of the tube is not increased thereby will. The end of the shoulder 3-3 'of the previously prepared one is placed on this collar Tube parts welded on. The extension 6 is omitted because the two shoulders 3-3 'are separated from each other by an opening into which the approach 4 to the federal government 12 is inserted.
Der Ansatz 4 ist vorzugsweise gleichfalls mit Außengewinde versehen. Das Verschweißen des Endes der Schulterung 3-3' auf dem Bund 12 des Ansatzes 4 erfolgt dann, wie in Fig.7 dargestellt, mittels zweier erhitzter Matrizen 13 und 14, die sich außen auf den Enden der Schulterungen 3 und 3' und innen auf dem Bund 12 abstützen. The approach 4 is preferably also provided with an external thread. The end of the shoulder 3-3 'is welded onto the collar 12 of the projection 4 then, as shown in Figure 7, by means of two heated dies 13 and 14, the are supported on the outside on the ends of the shoulders 3 and 3 'and on the inside on the collar 12.
Die so hergestellte Tube ist nach Durchführung der Endverschweißung 2 vollkommen dicht abgeschlossen. Diese Eigenschaft ermöglicht es, die Tube unter besonders günstigen Bedingungen zu füllen, d. h. durch den Ansatz und nicht mehr von hinten, wie bisher üblich, so daß die einzelnen Tuben dem Benutzer sowohl hinten als auch vorn gebrauchsfertig geliefert werden. Die Füllung durch den Ansatz erfolgt durch ein Speiserohr, das an den Gewindeansatz angeschlossen wird und in zwei Gängen arbeitet, d, h., es saugt zunächst die Luft aus der Tube, bis diese ganz flach ist, und läßt dann das Füllgut in die leere Tube eindringen. The tube produced in this way is after the end welding has been carried out 2 completely tightly closed. This feature allows the tube to be underneath to fill particularly favorable conditions, d. H. through the approach and no more from behind, as has been the case up to now, so that the individual tubes face the user from both the rear as well as being delivered ready for use at the front. The filling takes place through the approach through a feed pipe, which is connected to the thread attachment, and in two turns works, i.e. it first sucks the air out of the tube until it is completely flat, and then lets the filling material penetrate into the empty tube.
